Before you book: replacing an oil or LPG boiler with a heat pump in Boston
In Boston, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
If your home near Boston is off the mains gas grid, a heat pump removes the need for oil or LPG deliveries. Bungalows and detached houses near Boston running on LPG can move to a heat pump, with the tank collected by the supplier.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Older oil boilers nearing the end of their life
- Detached houses and bungalows with garden space for the unit
- Eligible homes in England and Wales within the higher grant window
What's included
- Removal of the oil or LPG boiler and flue
- MCS certificate and grant application in England and Wales where eligible
- Oil tank draining and removal or making safe, as set out in your quote
- Free survey with a detailed heat loss calculation for older construction
- Outdoor unit, heat pump cylinder, controls and radiator changes
Owners across Lincolnshire can have oil tank removal arranged alongside a heat pump installation in Boston.
Grants and rules for heat pumps in England
Homes in Boston can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
What to budget for replacing an oil or LPG boiler with a heat pump in Boston
The ranges below are typical installed prices for homes in Lincolnshire, including VAT. A survey sets the exact figure, because two similar-looking houses in Boston can need quite different radiators and pipework.
| Home | Typical size | Installed guide price | After £9,000 grant |
|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £9,500–£12,500 | £500–£3,500 |
| 2–3 bedroom terrace or semi | 5–7 kW | £10,500–£13,500 | £1,500–£4,500 |
| 3 bedroom semi or small detached | 6–9 kW | £12,000–£15,500 | £3,000–£6,500 |
| 4 bedroom detached | 8–12 kW | £14,000–£18,000 | £5,000–£9,000 |
| 5+ bedroom or larger older house | 11–16 kW | £16,500–£22,500 | £7,500–£13,500 |
Installed, inc VAT: unit, cylinder, controls, minor pipework and commissioning. The £9,000 Boiler Upgrade Scheme figure applies to oil and LPG replacements in England and Wales installed from 21 July 2026 to 31 March 2027.
How long is the heating season in Boston?
On the shortest day Boston gets about 7 hours 34 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.
What happens after you enquire in Boston?
- Send your postcode and a few details, or use the guide price tool.
- A surveyor visits your Boston home, measures every room and checks where the outdoor unit can go.
- You receive a heat loss design and a fixed written quote, with any grant shown where it applies.
- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Replacing an oil or LPG boiler with a heat pump in Boston: questions
Do I need new radiators for a heat pump in Boston?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Boston home gives a room-by-room list.
Do you cover Spalding as well as Boston?
Yes. We arrange surveys and installation in Spalding, which is about 14 miles south of Boston, and across Lincolnshire.
How soon can you survey a home in Boston?
Survey dates depend on how busy installers are in Lincolnshire. We offer the next available dates when you enquire and confirm them in writing.
Do I have to remove my oil tank?
Not always, but it should be emptied and made safe. A tank in good condition can be drained, cleaned and left in place, though most owners prefer to have it taken away to free up space. Old or damaged tanks are usually removed. Your quote says which option is included, and any remaining oil and sludge is disposed of properly.
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
